<p>Convenience function to read a string with unknown character encoding. If
the string is already in UTF-8 encoding, it will be returned right away.
If not it tries to detect byte-order-mark for UTF-16/32 cases and use that.
Otherwise, the environment will be searched for a number of environment
variables (whose names are specified in the NULL-terminated string array
<em class="parameter"><code>env_vars</code></em>
) containing a list of character encodings to try/use. If none
are specified, the current locale will be tried. If that also doesn't work,
WINDOWS-1252/ISO-8859-1 is assumed (which will almost always succeed).</p>

<p>Helper function for tag-reading plugins to create a <a href="/usr/share/gtk-doc/html/gstreamer-1.0/GstSample.html#GstSample-struct"><span class="type">GstSample</span></a> suitable to
add to a <a href="/usr/share/gtk-doc/html/gstreamer-1.0/GstTagList.html#GstTagList-struct"><span class="type">GstTagList</span></a> as an image tag (such as <a href="/usr/share/gtk-doc/html/gstreamer-1.0/GstTagList.html#GST-TAG-IMAGE:CAPS"><span class="type">GST_TAG_IMAGE</span></a> or
<a href="/usr/share/gtk-doc/html/gstreamer-1.0/GstTagList.html#GST-TAG-PREVIEW-IMAGE:CAPS"><span class="type">GST_TAG_PREVIEW_IMAGE</span></a>) from the encoded image data and an (optional) image
type.</p>
<p>Background: cover art and other images in tags are usually stored as a
blob of binary image data, often accompanied by a MIME type or some other
content type string (e.g. 'png', 'jpeg', 'jpg'). Sometimes there is also an
'image type' to indicate what kind of image this is (e.g. front cover,
back cover, artist, etc.). The image data may also be an URI to the image
rather than the image itself.</p>
<p>In GStreamer, image tags are <a href="/usr/share/gtk-doc/html/gstreamer-1.0/GstSample.html#GstSample-struct"><span class="type">GstSample</span></a>s containing the raw image
data, with the sample caps describing the content type of the image
(e.g. image/jpeg, image/png, text/uri-list). The sample info may contain
an additional 'image-type' field of <span class="type">GST_TYPE_TAG_IMAGE_TYPE</span> to describe
the type of image (front cover, back cover etc.). <a href="/usr/share/gtk-doc/html/gstreamer-1.0/GstTagList.html#GST-TAG-PREVIEW-IMAGE:CAPS"><span class="type">GST_TAG_PREVIEW_IMAGE</span></a>
tags should not carry an image type, their type is already indicated via
the special tag name.</p>
<p>This function will do various checks and typefind the encoded image
data (we can't trust the declared mime type).</p>
